Hello Grumpy,
Thanks so much for all that information, especially re the Magnetron and links to the service manual relating to the relevant concerns I have at the moment.

I will hunt down a Magentron type coil from somewhere in the next couple of days and see how it goes. Might tackle the clutch thingy tonight and remove the WD40. I have noticed that as I screw the clutch housing down onto the crankshaft, the square shaft becomes tighter and tighter to rotate.

I will also get some pics up as soon as I can, and myabe start a new topic on the restoration project. I think what I want to do now is put the mower back together, get it to run, then strip it down again and do a thorough clean and paint job. Currently have the cutter palte in an electrolytic bath to remove the rust and free up the blade bolts.

Will keep you posted, as they say on forums these days!

Many thanks again for your time,
